ZOOLOGY— BIIJDS. 



Arizona, and Western New Mexico, this little Titmouse is abundant and 

 quite fjenerally distributed, though it aA oids the heavy pines, among wliich 

 I have never seen it, seeking especially the hill)- regions covered with 

 ])irions and cedars, where they may be seen in fall and winter in very large 

 Hocks. In such localities, they probably breed, as I found them in the worn 

 dress peculiar to this period. They are also fond of frequenting the hea^'y 

 brush along the streams and canon sides. This is one of the most active 

 and industrious of the ftimily ; constantly on the move, searching here and 

 there with sharp, prying eyes for the various small insects and their larvit. 

 It is perfectly fearless, knowing no danger, and its social disposition is shown 

 in its custom of uniting in flocks often numbering fifty or one hundred 

 individuals, Avhich, as they move along intent on their hunting forays, keep 

 up an inces.-<ant querulous chirping.
